Something to Think About
 Please
take the next five minutes to
address the following questions on a
piece of paper:
 What is learning?
 What are some things that you have
learned throughout your life (not just
formally or in school)?
 How have you learned these things?

Learning
 Relatively
permanent change in behavior
or knowledge that results from past
experience
Classical Conditioning
 Ivan
Pavlov –
Russian physiologist
 Repeatedly pairing
a neutral stimulus
with a responseproducing stimulus
until the neutral
stimulus elicits the
same response
Pavlov’s Dogs
Classical Terminology


Neutral Stimulus (NS): does not initially elicit
a response
Unconditioned Stimulus (UCS): elicits a
certain, predictable response; automatic
Unconditioned Response (UCR): natural
reaction to a stimulus; automatic
Conditioned Stimulus (CS): once neutral, but
after being paired with a UCS, it elicits a
response; learned
Conditioned Response (CR): learned reaction
to a conditioned stimulus; learned

Expanding Classical
Conditioning
 Generalization:
responding to a second
stimulus that’s similar to the original CS
 Discrimination: ability to distinguish
between different stimuli
 Extinction: gradual disappearance of a
CR when the CS is repeatedly presented
without the UCS
 Spontaneous recovery: reappearance of
a previously extinguished response
after time without exposure to the CS

 Behaviorism:
emphasizes observable
behaviors
